<div role="main"><h1>Working with variables</h1>

<p>During a debug session, you can display variable types, and change 
or disable variable values.</p>

<p>To display variable type names:</p>

<ul>
  <li>In Variables view, click the <strong>Show Type Names</strong> toggle button.</li>
</ul>

<p>To change a variable value while debugging:</p>

<p>During a debug, you can change the value of a variable to test how your 
program handles a particular value or to speed through a loop.</p>

<ol>
  <li>In Variables view, right-click a variable, and select <strong>Change Value</strong>.</li>
  <li>Type a value.</li>
</ol>

<p>To disable a variable value while debugging:</p>

<p>You can disable a variable so that the debugger does not read the variable's 
value from the target. This is useful if the target is very sensitive or the 
variable is specified as volatile.</p>

<ul>
  <li>In Variables view, right-click a variable, and select <strong>Disable</strong>.</li>
</ul>
